Air Quality (NO2 diffusion tube) data

Data from Bristol City Council operated passive air quality monitoring devices. Diffusion tubes measure concentrations of a traffic pollutant (nitrogen dioxide or NO₂). This is separate from the air-quality-data-continuous dataset because these data are reported annually, not hourly.

Data displayed is annual nitrogen dioxide (NO₂) from diffusion tubes. Data from 2010 onwards are shown.

Data are bias adjusted and annualised where required but not distance adjusted. This change in the data occurred 2019-07-31. Full details of air quality monitoring results are reported to Defra on an annual basis. The most recent reports on air quality in Bristol are available from the council's web site.
